Mobile offline mapping and editing of shapefiles?

Question

I've got a client that wants to create a mobile app that can view and edit shapefiles stored locally on the device to enable it to work offline. There is a possibility of converting the shapefiles to KML or other format if needed.

It would need to work on Android, iOS and Blackberry so a HTML5/Phonegap solution is preferred.

Does anyone have any recommendations?

Answer 1

I would try to use a Mobile Web Service such as iJetty: http://code.google.com/p/i-jetty/

and deploy a webGIS application such as CartoWEB or similar.

Answer 2

Take a look at the HTML5 samples, Esri has an sample showing the offline/ local storage: Tiles in Local Storage. Should be possible to save as data as KML as well.

Answer 3

There is an Android application: SoM
